LASTlNG-TACK STRIP.

SPEGIFICATIQN forming part of Letters Patent No. 337,662, dated March 9.1886.

Application filed November-19, 1885. Serial No. 1153,2436. (No model.)

To all whom, it 711,114 concern.-

Be it known that I, FRANK CHASE, of Boston, in the county of Suiiolk andState of Massachusetts, have invented a certain new and ImprovedLasting-Tack Strip, of which the following is a specification.

Thelasting-tack stripin which niyinvention is comprised consists of wireof suitable crosssection, which at intervalsis bent into loops, the legsof which are pressed together and otherwise manipulated so as to formstems with pointed ends, said stems being either corrugated or not, asdesired. In this way I produce economically and with facility a striphaving tacks connected together and put into shape in which they can beconveniently and effectively used.

In the accompanying drawings, Figure l is aview of the wire from whichthe lasting tack strip is to hemade. Fig. 2 represents the strip afterthe wire has been bent into loops at intervals. Fig. 3 represents thecompleted strip-that is to say, the strip after the loops have hadtheirlegs squeezed together and their ends pointed.

.A, Fig. l, is the wire, of any suitable metal and of any suitable shapein cross-section. This wire by suitable means is bent at intervals intoloops, a, as indicated in Fig. 2, and each loop is then squeezed so asto bring its legs closely together in the form desired for the shank orstem of the tack, and its end is pointed, all as indicated in Fig. 3.

The squeezing and sharpening operations can be readily effected by meansof suitable dies, which dies may be the samein which the loops areformed, or separateinstrumentalities for squeezing and sharpening may beemployed.

In this way I produce with ease and at small cost a lastingtack stripconsisting of wire formed into a series of connected tacks. Theintervals between the tacks can vary as desired. The strip can readilybe used, and the tacks can be readily severed as required. The Wire can,if desired, be corrugated, or the tacks themselves can be corrugated inthe dies by which they are formed. Furthermore, if desired, the wire canbe so formed throughout its length as to be thicker at the points wherethe bends or bights of the loops will come, thus putting more metal intothe loops-the point where it is needed in order to insure the formationof a. proper point on the tack. '\I

Having described my invention, what I claim, and desire to secure byLetters Patent, is

A lasting-tack strip consisting of wire bent at intervals into loops,pressed into tack form,

and pointed, substantially as and for the purposes hereinbet'ore setforth.

In testimony whereot'I have hereunto set my hand this 5th day ofNovember, 1885.
